Name of the Condition

• Common Name: Allergic and Dietetic Gastroenteritis and Colitis
• ICD Code: K52.29

Summary

Allergic and dietetic gastroenteritis and colitis refer to inflammation of the stomach and intestines due to allergic reactions or dietary habits. This condition typically involves gastrointestinal disturbances caused by ingestion of certain foods or allergens.

Causes

• Allergic reactions to foods such as dairy, nuts, or shellfish.
• Dietary hypersensitivity or intolerance, possibly due to certain additives or preservatives.
• Environmental allergens or stress can sometimes exacerbate symptoms.

Risk Factors

• Family history of allergies or gastrointestinal conditions.
• Pre-existing food allergies or intolerances.
• High exposure to potential allergens in the diet or environment.

Symptoms

• Abdominal pain and cramping.
• Diarrhea or loose stools.
• Nausea and vomiting.
• Bloating and gas.

Diagnosis

• Medical history and dietary review.
• Elimination diet to identify offending foods.
• Allergy testing, such as skin prick tests or blood tests.
• Endoscopy or biopsy in certain cases, to evaluate inflammation.

Treatment Options

• Dietary modifications to exclude trigger foods.
• Antihistamines to manage allergic reactions.
• Corticosteroids in severe cases to reduce inflammation.
• Probiotics to support gut health.

Prognosis and Follow-Up

• The condition is typically manageable with strict dietary control and avoidance of allergens.
• Regular follow-ups are important to adjust dietary plans and monitor symptoms.

Complications

• Chronic inflammation can lead to nutritional deficiencies.
• If untreated, there is a risk of developing more serious digestive disorders.

Lifestyle & Prevention

• Maintaining a food diary to track potential triggers.
• Reading food labels to avoid allergens.
• Seeking dietary advice from a registered dietitian.

When to Seek Professional Help

• Persistent or severe gastrointestinal symptoms.
• Signs of dehydration, such as decreased urination or dizziness.
• Any sudden or severe allergic reactions (e.g., difficulty breathing, hives).

Tips for Medical Coders

• Ensure precise documentation of diagnosed food allergies.
• Avoid mixing codes for general gastroenteritis with those specific to allergies or dietetic conditions.
• Verify that the condition does not fall under another specific ICD code with more precise detail (e.g., lactose intolerance, celiac disease).
